i got a mazda 6 diesal (sorry for spelling haha) and it struggles to idle sometimes. just seems to idle ok for abit then drop the revs and bounce i little then die. seems strange n im not sure what to check really.
Does it stall when you press the brake? or just when it idles?If it stalls when it is just idling i would listen to see if it is sucking air,if so you have a bad vaccum line somewhere.If it stalls when you press the brake to stop and is not idleing when you are parked then i would look at the "throttle sencor".
